Device requirements

Pairing code

Matter products usually have the Matter badge printed on the packaging. The pairing code is on the device body, as shown below. If a product does not have a pairing code label, it cannot be added through the standard process.

Pairing state

The pairing mode can be set on the Tuya IoT Development Platform. By default, Tuya-enabled Matter products automatically enter pairing mode when power on for the first time. If the network indicator on the device is not blinking, reset it manually.

• Turn the light on and off five times until it blinks, with a 3-second pause between each on and off.
• Turn on the device and press and hold the power button for five seconds until the indicator blinks quickly.

Uncertified Accessory prompt

A Matter device that is not Matter-certified or is used for testing purposes is written with a test certificate.

• If you get a prompt for an uncertified product when adding a product to the Home app, Tuya-enabled app, or SmartThings app, tap Add Anyway to continue pairing. After your product is certified for Matter compliance and written with the official certification, the Uncertified Accessory prompt will disappear.

• When adding an uncertified Matter device to the Google Home app, you will receive a prompt that prevents you from adding the device. To continue, provide the 16-bit Matter PID of the test device, device type, and Google account to Tuya’s project manager or submit a service ticket for allowlisting.

• After your product is certified for Matter compliance, replace the test certificate with the official Device Attestation Certificate (DAC). Then, the prompt on the app will disappear.

  

Device pairing

When all the above prerequisites are met, you can start pairing. Power on the device and put it in pairing mode. If the indicator on the device blinks fast, the device is ready for pairing. You can use any Matter-enabled app to add the device.

Add device to Tuya-enabled app

The Tuya-enabled app supports Wi-Fi, hub, and Thread devices. The pairing process varies by protocol.

Add Wi-Fi device to Tuya-enabled app

Two methods are available:

• Scan the QR code or enter the pairing code, applying to Tuya-enabled and third-party Matter devices.
• Auto discovery pairing, applying to Tuya-enabled Matter devices only.

Method 1: Scan QR code or enter pairing code

1. Power on the device and connect your phone to an available 2.4 GHz Wi-Fi network.

2. Put the device in pairing mode.

7. Scan the QR code or enter the pairing code and select a Wi-Fi network.

   

8. Enter the Wi-Fi password to complete the pairing process.

   

Device sharing and bridging

Device sharing and bridging applies to:

• The Tuya-enabled app shares Matter over Wi-Fi or Matter over Thread devices with third-party apps.
• The Tuya-enabled app shares bridged Zigbee devices with third-party apps.
• Third-party apps share Matter over Wi-Fi or Matter over Thread devices with the Tuya-enabled app.

After a device is added to a Matter-enabled app, it can be shared with a different Matter-enabled platform through a QR code or a sharing code.

Tuya-enabled app shares Matter device with third-party apps

1. Open the device to share on the Tuya-enabled app. Tap the meatballs menu (⋯) in the top right corner and select Share Device.

   

2. Select Share over Matter to generate a code, or choose Share with QR Code. The receiver can copy and paste the code or scan the QR code to add the device.

   

3. Open the third-party app and add a device. Scan the QR code or paste the sharing code to add the shared device as instructed.

   

4. After the sharing process is complete, you can use the Tuya-enabled app’s Matter Service or the third-party app to check all the connectivity services of the device and manage the fabric.

   

Tuya-enabled app shares bridged device with third-party apps

Bridged Zigbee devices are not Matter-enabled products, so they do not have a pairing code and therefore cannot generate a sharing code. You can generate a sharing code of the bridge hub to share Zigbee devices with third-party platforms.

1. Open the hub connected to the Zigbee device on the Tuya-enabled app. Tap the meatballs menu (⋯) in the top right corner. Select Share via Matter Gateway to generate a code, or choose Share with QR Code.

   

2. Open the third-party app and add a device. Scan the QR code or paste the sharing code to add the shared device as instructed.

   

Third-party apps share device with Tuya-enabled app

Home app shares device with Tuya-enabled app

1. Open the device panel on the Home app. Tap the gear icon in the lower right corner and select Turn On Pairing Mode. Copy the generated setup code.

   

2. Open the Tuya-enabled app and add a device. Paste the setup code to add the shared device. A third-party app can share a Thread device with the Tuya-enabled app directly, without the need to add a Matter hub to the Tuya-enabled app.

   

3. After the sharing process is complete, you can use the Tuya-enabled app and the Home app to check all the connectivity services of the device and manage the fabric.

   

Amazon Alexa app shares device with Tuya-enabled app

Open the device panel on the Amazon Alexa app. Tap Settings in the top right corner and select Other assistants and apps to generate the sharing code. Tap Copy. The Tuya-enabled app or other apps can use this code to add the shared device.

Google Home app shares device with Tuya-enabled app

Open the device panel on the Google Home app. Tap Settings in the top right corner and select Linked Matter apps & services to generate the QR code or sharing code. Tap Copy. The Tuya-enabled app or other apps can use this code to add the shared device.

After the sharing process is complete, you can check all the apps linked to the shared device on the Google Home app.

Voice control

After a device is added to the Amazon Alexa, Google Home, or Home app, it can be controlled via the smart speakers without linking voice skills.
If a device is added to the Tuya-enabled app first, voice control can be enabled in two ways.

• Share the Matter device on the Tuya-enabled app with the third-party platform. Then, this device can be controlled via the app and voice assistant of the respective platform.
• Link the Matter device on the Tuya-enabled app with the target voice skill. Then, this device can be found on the third-party app and controlled via voice.

Remote control and automation

A Tuya-enabled Matter hub is necessary to enable remote control and automation for third-party Matter devices added to the Tuya-enabled app, while it is not required for Tuya-enabled Matter over Wi-Fi devices.

A hub is required for both local and remote control, as well as automation, for third-party apps such as Apple Home, Google Home, Amazon Alexa, and SmartThings.

For more information about the supported hubs, see Hub requirements.

Group

• The group feature on the Tuya-enabled app only applies to Tuya-enabled devices, not to third-party Matter devices.
• Third-party apps allow devices of the same type across different protocols to be grouped. For example, in the Home app, you can add lights using Wi-Fi, Thread, or Zigbee to a single group. However, it is not possible to include both a Wi-Fi light and a Wi-Fi socket in one group.

OTA updates

If an update is available, when you open the device panel on the Tuya-enabled app, you will be prompted to install the update. Or, you can check for an update on the Device Settings page.

• Currently, Tuya-enabled Matter over Wi-Fi devices do not support OTA updates through third-party apps. They can be updated using the Tuya-enabled app only.

• Tuya-enabled Matter over Thread devices and hubs support OTA updates through third-party apps.

• Currently, the Tuya-enabled app does not support OTA updates for third-party devices. A Tuya-enabled Matter hub is required to enable third-party devices to install OTA updates through the Tuya-enabled app.
